Ok, so this guy is walking down the street and he sees a want add for a piano player. He steps in and informs the manager of the place that he would like to audition for the job. The manager says "ok" and the guy sits down at the piano in the place and begins to play the most beautiful song the manager has ever heard.
"OH MY GOD. That was beautiful!!! What's it called?"
The man responds,
"It's called 'Iv'e got dog sh*t on my pecker and rovers done run off' blues in e minor.
Taken aback the manager asks for another song.
The man plays a song even better than the first. Afterward the manager is in tears begging to know the name
The man responds,
"It's called 'Slap your mother, kiss a goat and tell me that you love me."
Once again the manager is shocked by the name.
The manager says,
"Ok, I love your music. And I'm going to hire you, but don't EVER tell any one the name of your songs."
That night, the place is packed. The man is playing great and the audience can't get enough. He gets up to take a bathroom break. He comes out and as someone else is walking into the restroom, they exclaim, "Hey! You know your fly's undone and your cock is hanging out!"
The piano player responds,
"Know it?! I WROTE IT!"
